What The GRE Really Tests
The GRE General Test is not a math test. Nor is it a vocabulary test. Well, okay, you do have to know about these topics in order to get a good score. But this test is really testing your executive reasoning skills.
The term might be unfamiliar, but you already have—and use—these skills every day. Here are some examples:
You arrive at work in the morning and think about all of the things that you could do that day. You can’t get it all done, so which things will have to wait until this afternoon, or tomorrow, or next week? Which one thing should you start working on first?
You are faced with a list of 20 unread emails (or, if your inbox is more like mine, about 80). Which ones do you read first? The oldest ones? The ones from your boss? The ones marked urgent? Are there some that you won’t even click on right now because you know, from the sender’s name or from the subject line, that those emails aren’t very important? (And how did that one spam message get through the filter?)
You have a choice between working on Product X or Project Y. Project Y will result in about 5% more revenue to the company, but Project Y will also take 50% longer. Which do you do?
None of those decisions are easy ones (and many would likely require more information than I gave in the little scenario). This complex decision making is exactly what a good executive needs to be able to do well—and this is what the test writers and graduate schools actually care about.
The math problems, vocab questions, and reading passages on the General Test are ultimately tools to allow the exam writers to test you on your decision-making ability. The Subject Tests are the ones that assess you more on your domain-specific expertise.
How does that help me take the test?
Paranoia Runs Deep, Into Your Heart It Will Creep
“Many a true word is said in jest.”—I don’t know, but I heard it from my mother.
“I’ve never seen any of these words before, but I bet they all mean, ‘You’re a loser’.”
“Why is this question here? Why am I here? When’s the civil service exam? Garbage men still have a union. . .”
Have you lived that movie? Paranoia is only human—and the old saying is true: “Just because you’re paranoid doesn’t mean they’re not out to get you.” Paranoia is a primal reaction, developed to help protect humans from animals with sharp, pointy teeth. Unfortunately, it is not helpful when one is facing questions with sharp, pointy teeth. Even though the GRE is out to get you. Failing to control your paranoia is a hidden reason for underperforming on the actual exam.
On this blog, I and others have discussed many factors crucial for success: foundation skills, strategies, timing, precision, and so forth. And it’s like I say about L.A.—everything you ever read [here] about it is true. However, after honing these skills, after achieving mastery, too many test takers succumb to their paranoia and thus revert when taking the actual exam, especially for the first time. Even 99th percentile skills will crumble if undermined by irrational panic and the results will not be gratifying. (Have you ever watched the Chicago Cubs play a post season series?) To succeed, folks must understand the difference between dispassionate, objective analysis—“I’ve never gotten a surface area question right in life, why do I think I’ll have a divine inspiration today?”—and irrelevant fear—“They’re going to tattoo a scarlet “L” on my forehead.” Just as folks plan question and timing strategies, they must develop tools to banish their internally generated negative visualizations.
How do you tell the difference? Objective analysis responds to the stimuli on the monitor. Paranoia is a response to internal doubts. (Notice how this is parallel to the nature of the exam—search for the answer on the screen, not in the opinions in your head.) Sometimes, after you’ve read a question twice (everyone has a sinking feeling the first time), you hear yourself singing, “I’ve got the ‘I don’t know where I’m going but I’m going nowhere in a hurry’ blues.” That’s the truth, not paranoia. Bail out. As one of my acting coaches used to say, “Only schizophrenics don’t react to the reality around them.” Conversely, paranoia is when your thoughts of impending disaster revolve around your supposed shortcomings rather than the material on the screen. As I’ve said before, if while taking the exam you find yourself thinking about how big a dumb ass you are, check the question—if it doesn’t read, “Which of the following best describes how big a dumb ass you are?”, you’re thinking about the wrong thing. That is paranoia. No kidding—you knew that.

What to Expect on Test Day
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
I’ve talked to a ton of students recently who were surprised by some detail of test day—and that detail affected their performance. In most of these cases, the “surprising” detail was actually exactly what should have happened, according to the official rules. So let’s talk about what’s going to happen when you finally get in there to take the test. Read more

My GRE Experience
I thought I might share my GRE experience and the lessons it taught me about the GRE prep process.
I’ve always been a test girl. My favorite two days of first grade were taking the IOWA exams, which I used to try to write at home to administer to my class of stuffed animals. I wish that were a joke. I got into a car crash on the way to the LSAT, pulled myself out a ditch, hitchhiked to the exam, and still scored in the 98th percentile. I left the bar exam for a few hours in the middle to go shopping for a sweater because I was cold. I love tests. I own them. That is, until I took the GRE.
I was pretty cocky rolling into the GRE. I bought a pack of vocab flashcards and looked them over for a few weeks. I took a few practice tests. I read over the math. I showed up feeling like a boss. And then I got my score. And then I cried.
I did badly. What the heck? Tests are basically the one thing I can do!
Lesson one: The GRE must be studied.
The GRE really benefits from familiarity with the test. If you want to max out your score, you can’t just know the underlying material “ you have to be familiar with how it shows up and the best methods for handling it when it does.
I was daunted for a while, but I decided the GRE wouldn’t beat me. So after hiding from the exam for a few months, I got some study materials and got back on the horse.
Lesson two: The vocab must be learned.
